I did a little googling,and everybody states,it is a driver related issue,so updating your nvidia driver might help,if its not up to date. And you managed to start the game once at least properly? I mean older versions/whenever you tried in the past.
e: you can also try this, make a shortcut do desktop from the SU.exe and in the shortcut in the target field: after it says "SU.exe" put this line there -force-gfx-direct
like this,but with the games shortcut obviously
e2: lastly,you can try deleting this folder - C:\Users\
YourUserName\AppData\Roaming\Unity - might be old, corrupted settings the game will recreate them upon launch.
